open systems (the heat counter with two primary flow converters and two electronic units, one of which is a head unit), model UFEC 005-2. The heat counter UFEC 005-2 calculates the consumed thermal energy taking into consideration the annual time-table of cold water temperature submitted by consumer when the heat counter is ordered.

open systems (the heat counter with two primary flow converters and one electronic unit), model UFEC 005-2S. The consumed thermal energy is calculated using the algorithm of the closed system.

open systems (the heat counter with two primary flow converters and one electronic unit), model UFEC-005-2M. The heat counter UFEC 005-2M calculates the consumed thermal energy taking into consideration the annual time-table of cold water temperature submitted by consumer when the heat counter is ordered.

Characteristics:

The heat counter UFEC 005 has an archives for storing of average hourly and average daily parameters of coolant with time depth up to 5000 hours.

The heat counter is equipped with two interfaces: RS-232C for information output from the archives to small-size portable printer IDP3110 "CITIZEN" (it can be delivered according to an order), RS-485 for information output from the archives to personal computer. There are current output signal (0-5 mA) and frequency signal.

The heat counter is equipped with a real operation time counter.

The heat counter is equipped with a two-line, multi-functional liquid crystal
(LC)-display (16õ2) where values of parameters and their units are indicated.

The heat counter is equipped with an ergonomic membrane keyboard which makes it possible to work with the device both in the "Operation" and "Programming" modes.

The heat counter is equipped with a device for the automated re-recording of the set-up parameters that prevents an unauthorized resetting and improves significantly reliability of the flowmeter operation.

Wide range of the pipeline diameters (from 15 to 1600 mm).

Length of VSCMm cable from 5 to 200 m, according to requirement of the customer.

Long acceptable distance between the primary flow converters and the calculating device (up to 200 m).

Storing of the programmed parameters, archives infirmation under removal of electric power supply for two years.

High reliability and stability of the measurements (the calculating devices of the heat counter UFEC 005 and the water flowmeter-counter UFM 005 are manufactured on the completely imported elemental base produced by the leading firms - INTEL, MAXIM, MOTOROLA, etc.).

The heat counter UFEC 005 is calibrated on the operation place without dismantling of the primary flow converters according to the spillage-free methodology approved by the RF Gosstandart. Inter-calibration period - 2 years.

The heat counter UFEC 005 and the flowmeter-counter UFM 005 are equipped with the self-diagnosis tools. Information about malfunction is presented in the LC-display if the faults occur in the device operation.
